用PI Expert設(shè)計后提示如下警告:
The primary circular mils per amp (CMA) calculation is above the recommended maximum for this power level (PO).
它提示的解決辦法有一下幾個:
1、Decrease the effective bobbin width (BWE) by decreasing the core/bobbin size.
2、Decrease BWE by decreasing the number of primary layers (L).  
3、Increase the number of primary (NP) and secondary (NS) turns, which will force smaller wire (higher AWG) to be used.
4、Decrease the reflected output voltage (VOR), by increasing NP, which will force smaller wire (higher AWG) to be used.
5、Increase the current waveform parameter (KRP/KDP), which will increase the primary rms current (IRMS) and lower the CMA.
6、Raise the output power requirement (PO).
不明白其中的CMA是一個什么參數(shù).
請大俠賜教!!
